Kvyat relieved by Toro Rosso improvement on final days of F1 test

Toro Rosso rookie Daniil Kvyat says he is heading to the Australian Grand Prix relieved with how his team's difficult Formula 1 pre-season improved on the final couple of days.

The Russian and team-mate Jean-Eric Vergne were hit by reliability issues throughout testing, but Toro Rosso appeared to make some progress towards the end of the final test, where it was tied seventh on the mileage charts with McLaren.

GP3 champion Kvyat went into last week's test with just 71 pre-season laps to his name, but he was able to make up some ground by logging another 136 across his final two days of running before the first race.
